Error, error everywhere: A look at megastudies of word reading

Comparisons between the two primary methods used in studies of word reading, using the standard frequency X regularity interaction in word naming as test case, found that the effect replicates across small-scale studies, but somewhat different results were observed using item means from 3 megastudies.

Abstract

The prevalence of human immunodeficience virus (HIV) infection among patients under renal replacement therapy varies, with estimates of 1% for Europe and 1.5% for the United States. Survival in HIV infected individuals receiving renal replacement therapy has improved since the introduction of high activity antiretroviral therapy (HAART). Current experience in renal transplantation in HIV-infected patients in the United States indicates that the three-year survival rate is similar to that of HIV-negative transplant recipients, with virological and immunological control of the infection by HAART and no increase in the number of opportunistic infections or tumors. The criteria for selecting renal transplantation candidates in this population are the following: no aids-defining events, CD4 cells > 200 cells/.l and undetectable viral load under HAART. In Spain, where most of these patients are former drug abusers, a two-year period of abstinence from cocaine and heroine abuse is also required, although patients can be participating in the methadone program. The main problems in the post-transplantation period have been interactions between HAART and immunosuppressive drugs, management of hepatitis C virus (HCV) coinfection and the high rate of acute rejection. To date, seven such renal transplantations have been performed in Spain, with favorable patient and graft survival and no progression to aids.
